altiro3D: 2D-to-3D image and video conversion library for free-view LCD (starting from a single imagine or frame)

altiro3D is a free, extended C++ Library (-see releases) developed to reconstruct reality from a given single imagine (e.g., .png, .jpg) or flat video (e.g., .mp4). This is done generating a light-field (or Native) image -see "User's Manual"

The several altiro3D command lines provide the following features: • Create Native (i.e., 3D image) from Photo using MiDaS-small. • Create Native from Photo using MiDaS-large. • Create Native from a given original camera’s RGB image and depth image. • Create Native from a given Quilt (N×M). • Create Native from sorted N-views (i.e., sequential set of plain images) stored in a given directory. • Convert Quilt views to 2D video (.mp4). • Convert given 2D video to Native 3D video (.mp4). All these forms of Native images/videos consisting of light-fields can be correctly displayed on a specific slanted, lenticular screen such as the Looking Glass (LG) Portrait.
